I think after a year bulid up to a main event that there will be no run in to ruin this match. I expect Cena and Rock to pull off a solid 30 minutes of in ring action. Cena will win with a peoples elbow or some stupid shit.
If Lesner is there I would expect him to have a similar encounter with the Undertaker as that had after that ufc event.
batista is there to suck vinces dick for his job back.
